Marshawn Lynch Hasn't Submitted NFL Retirement Papers, According to Seahawks

If Marshawn Lynch's NFL career is really over, the star running back is taking his time with making it official. 

Per Bob Condotta of the Seattle Times, the Seattle Seahawks said Lynch had not filed his retirement papers as of Saturday, adding that the team has "prepared for him to do it whenever."

Never one to seek the spotlight, Lynch casually made his retirement announcement on Twitter as the Denver Broncos and Carolina Panthers were playing in Super Bowl 50:

Lynch did not officially speak about his retirement, though his agent, Doug Hendrickson, and Seahawks owner Paul Allen congratulated him on a great career after his initial Twitter post:

In March, Pro Football Talk's Mike Florio (via Tadd Haislop of Sporting News) noted the Seahawks had not moved Lynch to the reserve-retire list, possibly so they could wait until June 1 to cut him to spread out the cap hit or perhaps because the 30-year-old has been "dragging his feet" and hoping to be cut.

However, per ESPN.com's Sheil Kapadia, Seahawks head coach Pete Carroll said Lynch is "committed to being retired" and the paperwork is "not an issue."

From 2011 to 2014, Lynch was one of the NFL's best running backs. He ran for 1,200-plus yards in each of his four full seasons with the Seahawks, leading the league in rushing touchdowns in 2013 and 2014, though injuries limited him to just seven games last season. 

Even though Lynch never wanted to be the face of the franchise, his power running style and personality made him a fan favorite. His retirement announcement caught the NFL world off guard, but it fit the way he's handled himself since entering the league in 2007.
